9.
In this application, the SAM2W modem is connected to an electricity meter, which is located at a
remote site, and the area is covered by the GSM/GPRS network.
At the office, the Operator is equipped with a computer, connected to a landline (PSTN) modem,
or another SAM2W modem.
To read the remote meter, the Operator uses the computer and the connected modem, and calls
the SAM2W at the remote site. The SAM2W modem will answer and provide a transparent data
path from the remote meter to the computer at the office.
After all data is read from the remote meter, the operator will instruct the computer to hang up the
call, which causes the remote SAM2W modem to terminate the call.
